The way I read Valve's reference above (and others made in the past) is that the metric that affects the visibility is STRICTLY sales. Not external traffic and not Wishlists. If the bump in sales is "big enough" (a vague term in and of itself), then Steam will bump the game's visibility. They've been very clear about it so I'm not sure where is the data coming from about traffic numbers and Wishlists being a factor.
